Thanks, there was only green line above horizon and this was corrected with lens correction :-) Martin On Monday 21 of May 2018 22:20:56 Timur Irikovich Davletshin wrote: > On Mon, 2018-05-21 at 21:14 +0200, komodo wrote: > > Thanks to all, > > > > works fine in lens correction module :-) > > > > I always tried chromatic aberrations module, i didn't know that this > > is also > > in lens correction. > > > > Martin > > Don't forget about defringe module if case of purple fringing on > something like tree branches. > > BTW, I would appreciate, if someone will explain me how chromatic > aberration module works.

BTW, I would appreciate, if someone will explain me how chromatic aberration module works. It just doesn't give me any picture improvement on Canon and Nikon files.

Re: [darktable-user] Chromatic aberration on Fuji
Thanks to all, works fine in lens correction module :-) I always tried chromatic aberrations module, i didn't know that this is also in lens correction.

Re: [darktable-user] Chromatic aberration on Fuji
Are you sure ? >From the manual This module currently only works for images recorded with a Bayer sensor (which is the sensor used in the majority of cameras). So not for Fuji Xtrans sensor, or is there something new ?

Sometimes people confuse TCA with fringing — defringe works fine in that case, but requires fine tuning for every image. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

If your lens/camera are not in the database (or TCA is not available) you can try to make you own calibration profile — http://lensfun.sourceforge.ne t/calibration-tutorial/lens-tca.html >From my personal experience it is not very difficult.

Re: [darktable-user] Chromatic aberration on Fuji
You can use the chromatic aberrations module under the corrections tab in darkroom. If it's not there, look in more modules and enable it.

This depends on whether correction data for a given lens (on that particular crop-factor) exists in Lensfun database. -- Šarūnas Burdulis math.dartmouth.edu/~sarunas signature.asc Description: OpenPGP digital signature
